Answer:
25π
Step-by-step explanation:
area of a circle π(r²)
diameter = 2r so we half the given diameter
radius = 5ft
5² = 25
so the answer is 25π
Answer:
d
Step-by-step explanation:
the answer is d because it is red and it needed to have one more ine going up the next one will be blue and have another line go straight across and so on
They reject if the pie is more than 3.2oz from 28oz.
The scale shows positive number if its more than 28oz.
The scale shows negative number if its less than 28oz.
The scale shows zero if its 28oz.
A . Scale reads -2.8oz which means less than 28oz, So accepted.
B. Scale reads 3.5oz which means 3.5oz more than 28oz. So rejected.
C. Scale reads -3.3oz which means less than 28oz, So accepted.
D. Scale reads 28oz which means more than 28oz, So rejected.
This is the concept of quadratic equations, to find out whether the two expressions we need to expand each of them:
(x)=(25+10x)(300-36x)
(x)=25(300-36x)+10x(300-36x)
(x)=7500-900x+3000x-360x^2
(x)=7500+2100x-360x^2
Expanding equation 2?
(x)=(100+20x)(100-12x)
(x)=100(100-12x)+20x(100-12x)
(x)=10000-1200x+2000x-240x^2
(x)=10000+800x-240x^2
considering the lead coeffienct
7500+2100x-360x^2≠10000+800x-240x^2
Answer:
